Viva Engage: New left navigation controls — collapse, resize, increased favorites cap, and reorder favorites capabilities

We're introducing a set of left-navigation improvements in Viva Engage on the web that give people more control over their navigation pane. These are additive, user-driven changes — users can collapse the left nav, resize its width, favorite up to 50 communities, and drag to reorder their favorited communities. None of these changes alter which destinations appear in the navigation. These enhancements are applicable to all surfaces that have the Engage left navigation menu - Web, and the Engage app in Teams and Outlook.
